Boston Marathon Suspects: Profile of Tamerlan and Dzhokar Tsarnaev On Social Media

WASHINGTON, D.C. (WUSA9) -- On the Russian equivalent of Facebook called V-Kontakte or VK, Dzhokar Tsarnaev's "Liked" pages include several related to Islam. One page shares the quote: "Let it be in our hearts...make good because Allah loves those who do good."

There's also a video featuring his older brother Tamerlan Tsarnaev, in which he speaks in different Russian accents or dialects, seemingly mocking them. Tamerlan's formative years were spent as a refugee in the capital city of Dagestan, a predominately Muslim republic with an Islamic insurgency that spilled over from neighboring Chechnya, which has experienced nearly two decades of war and instability.

The brothers came to the US in 2003, where both went to high school in Cambridge. Dzhokar became a student athlete, a wrester, and even won a scholarship for college. His 26-year-old brother was an avid boxer, and reportedly has a 3-year-old little girl.

Andris Spruds, Ph.D. is an expert on international affairs of post-Soviet Russia and its neighboring countries. He cautions against reading too much into the social media profile of a teenager who's youth is evident. But one thing does come through to Struds, especially in the video of brother Tamerlan- disillusionment with the American way of life going on around him.

Dr. Spruds says, "Basically he had not made a friend in the US. You can feel the alienation, the isolation and disappointment."

Tamerlan also talks about going to Russia and not finding a job there. CBS News reports he traveled there for six months in 2012, and could have potentially obtained some sort of millitaristic training.

But the boys' father also lives there, and Dr. Spruds says in his absence, Tamaran would have culturally acted as the head of his family in the US and certainly an authority over his younger brother.

"The older man in the family is really the man who is making decisions," adds Dr. Spruds.
